Historically, agarwood was mainly distributed in Hainan Island and Guangdong and Guangxi. According to ancient records, during the Song, Ming and Qing Dynasties, a steady stream of Hainan Aquilaria sinensis was transported to the mainland through various channels. At that time, Hainan Island was a fragrant island. Su Dongpo, a great writer in the Song Dynasty, once wrote when he lived in Hainan: "Hainan is barren, and the customs are mainly trading incense ... the people are useless and treasures breed." Broadcasting Jue smoked wood, and the rot still exists. " It is about the scene when Hainan residents traded agarwood for their daily needs, and local residents cut firewood to collect incense.
Li Shizhen, a famous doctor in Ming Dynasty, also said in Compendium of Materia Medica: Hainan Aquilaria sinensis is one million dollars, ranking first in the world! However, according to ancient records, due to excessive logging and excavation, Hainan Qinnanxiang, known as the best in the world, almost withered in the late Qing Dynasty. Qu Dajun, a famous poet in Qing Dynasty, traveled to Hainan Island and had a special liking for Hainan agarwood. In "Guangdong New Talk", he spared no expense to record the grand occasion of picking incense in Hainan, and said: "If you want to make a famous fragrant block, you must be in Hainan."
